Automatic Backfeed Restoration (ABR)
Automatic Backfeed Restoration is used to automatically close a normally open recloser if it detects a source
(via the SD element) on the either side of the recloser and absence of a source on the other side.
ABR function is designed to provide maximum safety for operators and equipment. Restoration disarm function
will prevent circuit-breaker closing for the ABR function in case power supply is absent from both sides longer
than specified Restoration disarm timeout (Trd) setting.
This element is only applicable for ring line type reclosers.
ABR element settings are described in Table 77.

Close Condition Verifier (CCV)
The Close Condition Verifier element controls breaker closing requests generated from local or remote
interfaces, an input/output module, or protection elements. If the network situation complies with the CCV
closing settings, closing is unblocked and vice versa.
A Hot tag for side + or
– is generated if the Source Detector identifies that a source is found and the Voltage
Reclosing Control element identifies that the power quality is within the acceptable limits.
A Dead tag for side + or
– is generated if the Source Detector identifies that a source is lost.
The CCV functionality can be Enabled or Disabled via the configuration menu. The CCV element settings are
described in Table 78.

Synchronization Indicator (SI)
The Synchronization Indicator is active only if the CCV setting Hot+ / Hot- allowed = Enabled. The SI element
monitors voltage magnitude and phase angle differences from both sides of the recloser. The CCV element
